We explore the implications of shocks to expected future productivity. In a setting with limited enforcement of financial contracts, firms have to post collateral to obtain external finance. In a real one-sector model with this type of "collateral constraint", positive news about future...

This paper studies the macroeconomic effects of shocks to idiosyncratic business risk in an economy with endogenously incomplete markets. I develop a model in which firms face idiosyncratic risk and obtain insurance from intermediaries through contracts akin to credit lines. Insurance is...

The interest rate at which US firms borrow funds has two features: (i) it moves in a countercyclical fashion and (ii) it is an inverted leading indicator of real economic activity: low interest rates today forecast future booms in GDP, consumption, investment, and employment. We show that a...

This paper develops a simple model with collateralized borrowing constraints to explore the business cycle implications of financial leverage. The degree of leverage is shown to be an important factor in the amplifying role of collateral constraints, suggesting that the financial vulnerability...

The interest rate at which US firms borrow funds has two features: (i) it moves in a countercyclical fashion and (ii) it is an inverted leading indicator of real economic activity: low interest rates forecast booms in GDP, consumption, investment, and employment. We show that a Kiyotaki-Moore...

This paper argues that counter-cyclical liquidity hoarding by financial intermediaries may strongly amplify business cycles. It develops a dynamic stochastic general equilibrium model in which banks operate subject to financial frictions and idiosyncratic funding liquidity risk in their...

Various papers have identified shocks to investment as major drivers of output, investment, hours, and interest rates. These investment shocks have been linked to financial frictions because financial markets are instrumental in transforming consumption goods into installed capital. However, the...

This paper argues that counter-cyclical liquidity hoarding by financial intermediaries may strongly amplify business cycles. It develops a dynamic stochastic general equilibrium model in which banks operate subject to agency problems and funding liquidity risk in their inter- mediation activity....

What are the long-run aggregate effects of monetary shocks displaying throughthe credit channel of monetary policy? We address this question by investigatingthe transmission mechanism and estimating the dynamic behaviour of variablesrelated to credit and innovation. Then, we develop a DSGE model...
